APA107 LED chip, APA107 compare with APA102C/SK6812

APA107 is the upgraded chip of APA102.

APA107 LED Product Overview
APA107 is a type ic for the three-color RGB Diming control strip and string ,This ic using the CMOS process to provide three-color RGB LED output driver to adjust the output with 256 gray scale and 32 brightness adjustment ,APA with 2 signal output way , one is clock ,another is data, the clock and data is synchronizated ,so that the crystal cascade piece of output movement is sychronizated .

APA107 LED Feature
CMOS process,low voltage ,low consumption
Synchronization of two-lane
Choose positive output or negative RGB three-color LED output
8 bit(256 level) color set ,5bit(32 level) brightness adjustment
Build-20ma constant current output
With self-detection signal build in support for continuous oscillation PWM
output ,can be maintained static screen

APA107 LED Main Application Field:
● Full color LED string light, LED full color module, LED super hard and soft lights, LED guardrail tube, LED appearance/scene lighting
● LED point light, LED pixel screen, LED shaped screen, a variety of electronic products, electrical equipment etc..

APA107 LED Description:
● Top SMD internal integrated high-quality external control line serial cascade constant current IC;
● control circuit and the RGB chip in SMD 5050 components, to form a complete control of pixel, color mixing uniformity and consistency;
●built-in data shaping circuit, a pixel signal is received after wave shaping and output waveform distortion will not guarantee a line;
●The built-in power-on reset and reset circuit, the power does not work;
●gray level adjusting circuit (256 level grayscale adjustable);
● red drive special treatment, color balance;
● line data transmission;
● plastic forward strengthening technology, the transmission distance between two points over 10M;
●data transmission frequency up to 800Kbps, when the refresh rate of 30 frames per second, a cascade of not less than 1024;
● built-in power polarity protection module, power polarity will not damage.

APA107 LED Electrical Characteristic:

APA107 LED Function Description:
  (1) cascading data structure
       Tandem N-LED:
Global bit:5 bit (32 level) brightness setting,while controlling R,G,B three-color
constant current output value,if set the global bit for the 10000( 16/31 ) is the output
current is half again the original PWM settings
APA107 LED PWM input and output signals Relations

(2). The number of pixel per second sent to the CKI frequency (FCKI) minus the Start
Frame bit divided by the number 40 the number of LED Frame bit 32, if the CKI
frequency(FCKI) to 512KHZ. The pixel number (512000-40)/32=15998, if the 50
second update Views can be connected in series LED number 15998/50=319. To
increase the number of cascaded IC CKI frequency
(3).POLAR to empty ,R,G,B for the negative output;POLAR access VSS ,R,G,B is
positive output
(4).VEN: self-detection
DATA field to the middle of 3 bit is B,G,R in the MSB of the opposite
phase, otherwise regarded as invalid data. VEN close to the empty when the
self-detection; when VEN VSS then activated self-detection
(5).CSEL to empty when the CKO and CKI,RP:CSEL connected with VSS when the
CKO compared with CKI.

APA107 LED SMD:
Compare with APA102C SK6812,  the advantage of APA107,

1, Intelligent reverse connect protection, the power supply reverse connection does not damage the IC.
2, The control circuit and the LED share the only power source.
3, Control circuit and RGB chip are integrated in a package of 5050 components, form a complete control of pixel point.
4, Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate.
5, Built-in electric reset circuit and power lost reset circuit.
6, Each pixel of the three primary color can achieve 256 brightness display, completed 16777216 color full color display, and scan frequency not less than 400Hz/s.
7, Cascading port transmission signal by single line.
8, Any two point the distance more than 5m transmission signal without any increase circuit.
9, When the refresh rate is 30fps, cascade number are not less than1024 points.
10, Send data at speeds of 800Kbps. 
11,The color of the light were highly consistent, cost-effective.. 
Applications 
12, Full-color module, Full color soft lights a lamp strip.
13, LED decorative lighting, Indoor/outdoor LED video irregular screen.
